In this diagram, bac~edf. if the area of bac= 6 in.², what is the area of edf? PLZ HELP PLZ PLZ PLZ

Bad White [126]

Answer:

2.7 in²

Step-by-step explanation:

Since ∆BAC and ∆EDF are similar, therefore, the ratio of their area = square of the ratio of their corresponding side lengths.

Thus, if area of ∆EDF = x, area of ∆BAC = 6 in², EF = 2 in, BC = 3 in, therefore:

$\frac{6}{x} = (\frac{3}{2})^2$

$\frac{6}{x} = (1.5)^2$

$\frac{6}{x} = 2.25$

$\frac{6}{x}*x = 2.25*x$

$6 = 2.25x$

$\frac{6}{2.25} = \frac{2.25x}{2.25}$

$2.67 = x$

$x = 2.7 in^2$ (nearest tenth)

Use the following information:

Anastasy [175]

Answer:

n(U) = 20
n(A) = 8
n(B) = 5
n(A'∪B) = 15

Step-by-step explanation:

For these sets, it is easy enough to list the elements and count them.

U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20}

n(U) = 20

A = {1, 3, 5, 7, 9, 11, 13, 15}

n(A) = 8

B = {7, 11, 13, 17, 19}

n(B) = 5

A'∪B = {2, 4, 6, 7, 8, 10, 11, 12, 13, 14, 16, 17, 18, 19, 20}

n(A'∪B) = 15

What is the surface area, measured in square

Aliun [14]

Answer:

SA = 126 square cm

Step-by-step explanation:

SA = 2(l · w) + 2(h · w) + 2(l · h)

SA = 2(5 · 6) + 2(6 · 3) + 2(5 · 3)

SA = 60 + 36 + 30

SA = 126 sq cm
